SPEGIFIGATION forming part of Letters Patent No. 642,033, dated January23, 1900. Application filed August 23, 1899. Serial No. 728,238. (Nospecimens.)

To all whom it may concern:

Be it known that we, GOTHARD WYSS and VINCENT WYSS, of Pittsburg, in thecounty of Allegheny, State of Pennsylvania, have invented a new anduseful Composition of Matter to be used for Treating Hemp Products ofEvery Description, of which the following is a specification.

Our composition, which we make in two qualities, consists of thefollowing ingredi ents, combined in the proportions hereinafter stated.I

The ingredients of quality No. 1 and method of compounding are asfollows: twenty-four ounces boiled linseed-oil, twelve ounces meltedtallow, and one ounce nitrobenzol.

Mixing recipe: First, put tallow in kettle; second, pour over tallow thelinseed-oil, boil until a thin fluid like water; third, then stir in thenitrobenzol until thoroughly mixed. Let 0001. Then the grease is readyfor use.

The second quality differs from the first in the substitution for aportion of the linseedoil of an analogous material which affords greaterbody to the composition. The ingredients of No. .2 and method ofcompounding are as follows: twelve ounces boiled linseedoil, twelveounces melted tallow, twenty-four ounces grease-soap, and one-half ouncenitrobenzol.

Mixing recipe: First, put tallow and greaseover this mixture after ithas melted the linseed-oil, boil all together until a thin fluid likewater; third, then stir in the nitrobenzol until thoroughly mixed. Letcool, after for use; The term grease-soap herein employed comprehends amixture of pure animal fat oil, those constituting the only ingredients.The substitution therefor of grease-soap in quality No. 2 for a portionof the boiled linseed-oil constitutes no more than a mere addition tothe compound of that which will give greater bodyto the composition. T.Hemp products-such as ordinary ropes, wagon, scafiold, and pulley ropes,ships ropes, wagon-covers, and engine-hoseare although in very extensiveuse subject after having. been exposed to wet to serious objections.Among those objections'there may be three especially enumerated: First,the hempen article becomes hard and stiff and therefore difficult tohandle; second, it rips or tears easily, and, third, it decays graduallyand being therefore liable to break without warning may in some usescause greatdanger, Different means have been from time to time employedto eliminate the objectionable features specified, but such means haveeffected the elimination of but one or two of said features and nonehave been sufficient to remove all. The various elements of ourcomposition so cooperate one'with another as to remove all of theobjectionable features named.

The compound is in the nature of a grease, which may be applied to theouter surface of the article to be treated in any suitable and ordinarymanner, so as to thoroughly coat the fibers of the hemp, each of whichto which it is applied it effectually protects, and being free from allmaterial that might injure the fiber may be safely relied upon topreserve the same. The first quality is for engine hose, wagon-covers,tents, barracks, ships ropes, and the like. The second quality may-beemployed to advantage for scaffold and pulley ropes, trolley-ropes, hempstraps, and the like. Incidentally this grease is adapted to preventrust on any material susceptible to such a deposit,'and the secondquality is also especially adapted for use by mechanic's, plumbers, gasand steam fitters to lubricate their cutting-tools and also to be usedas a substitute for red lead in packing of gas, water and air pipecouplings.

What we claim is- 1. The herein-described composition of matter,consisting of oil and tallow combined sub: stantially in the manner andin the proportions specified, with a sufiicient quantity of.n'itrobenzol toact as a preservative.

2. The herein-describedcomposition of matter, consisting of boiledlinseed-oil and tallow, combined substantially in the manner and in theproportions specified, with a suflicient quantity of nitrobenzol to 'actas a preservative.

In testimony of all which we have hereunto subscribed our names.
